I have a line chart with dates as the x-axis, i need to show some date (launch date) as the point where i need to show the reference line.
so how can i show that in line chart?
You'll need to use a continuous x-axis, then the option in reference line dialog should be available to draw a vertical line at the given position.
If your dimension values don't change, you can also overlay a line object (from line/arrow chart objects).
see this link hope this helps you
